What is a concern when aerial fiber-optic cable is installed between poles, even though there are no high voltage power lines?

When installing aerial fiber-optic cables, one primary concern is the buildup of static electricity. Although fiber-optic cables themselves do not conduct electricity in the same way that copper cables do, they can still be affected by static charges in certain environmental conditions. This is particularly pertinent when considering the installation context; even without high voltage power lines, wind and atmospheric conditions can result in the accumulation of static electricity on the cables, which may lead to discharge events that can disrupt the fiber-optic signal or cause localized damage.

Other concerns, such as physical damage from high winds or potential animal interference, are valid but are less specific to the unique properties of fiber-optic cables and their insulation. Similarly, while signal interference from nearby cables is a factor in some installations, fiber-optic cables are typically designed to minimize such interference due to their nature of transmitting light rather than electrical signals. Thus, the concern regarding static electricity is particularly relevant in the context of aerial installations and their susceptibility to environmental factors.
